III! different types and makes of motor vehicles. This feature of my invention makes the mounting of the device simple under conditions that would, With the old form; of construction,:be more complex. a I I There isin use a large'variet'y of sizes of curely to bracket 25, The slots 30 are the 7' to be brought close together to accommodate ;a small pulley orbe spread apart for'a large one;,and theyalso make it possible to adjust atheyok'e as avvholeto one sideorthe other, to" put the" yoke, and pulley'16, in alinement -=with Wheel 12'. These-slots make-it alsopos- I far. enough to disengageiit's open'en'ded slot from one of". the bolts.- The arm may sible to easily move the arm,28 ,out far enough; to disengage it from shaft 32 and then be turned-down and the: pulley 16 j .slipped offthe-shaftendwise. The shaft 32 .yyder' 83'Which bears against arm 29; A nut on :Which pulleylldis mo'unted has alshoult '34 isuscreW-threadedly engagedon the ends '35 of aXle :32, thus. fasteningsaid shaft firmly on arm 29. The arm-28- holds the other end of: shaft; 32, and also keeps pulley 16. in place.

' l tis very obvious-that the pulleylfikmust I be thoroughly lubricated when the device is k: inaoperation. var ous meansmay' be. em-

- ilployedito do thisfl other forms of devices t by means of; oil or grease vcups. Although of this character lubrication is accomplished jjthisis. an effective means of lubric'ation it zlrequires attention and is very apt to be neg- A -lect'ed, thus allowing thejshaft ;or+pulleyj;to

periodoftime; j V --1 B y having the.devicemade'with the-nu- 1 :merous, ad ustments above I described, it is :tates the use-of varioussizedpulleys is very I advantageous as it' makes it'possible'to use 'run' dry.- In myform of devicelhavesim- 4 plified lubrication by eliminating gthese oil or grease cups, or any other similar means 1 ffanda'have provided a-meansIWherebylubri- :cation is positive," I accomplish thisby V 50 making the inside of'pulley lti hollow asins'." .dimmd in Fig;-2. i -.The:hollow portion" 37 is filled with grease or any suitablei'lubricant V before thepulley is slipped onto-:shaft 32.

When once filled in this manner the pulley .Will .bei'automatically .rlubricatedi-for: a long possible to. set the pulley in any, position thatlwill make the operation of the device most-effective. f i i V a The adjustability of'yoke 17 which facilii the same; device on any sized vehicle vvithout changing any of the parts'other than the pulley, "While in other devices of this charac ter it is necessary to change'both the yoke.

and thepulley; 1 Itfwill beunderstoodthatthe forinof device' above described is merely typical and that an" object of this invention is to have a device that is' adjustable into any desired po- 'sitilon, 'It'i' for this and other obvious rea-' sons that Ido not Wish to limit myself to the particular means of adjustment herein def scribed, but reserve to. myself any changes ingfperipherally around the Wheel being of ,greaterlength' than the wheiel circumferor. modificationsthat will produce the same result or fall Within the scope of the follow- 5 in claims. J

,ilav'ing. described my inventior'l, I'claim: V

1; In com-bination' vith an automobileand a [driving wheel thereof, an endless belt passence, a shaft mounted upon the automobile in the icentral i'vertical plane of .thewheel capable ofbeing longitudinally movable and rotatable or fixed from rotation, and'a verti- 1. r

cally and horizontally adjuStabIeQ-y ke carrying an idler puller o nan axis transverse tothe shaft, said pulley beinginside said belt. '7

2; In combination' With -an automobile and a; driving f wheel thereof, an- -=endl'ess belt passing peripherally aroundjthe wheelbeing j capable ofbeinglongitudinally movableand .of;.greater length than the Wheel circumfer-- ence, a shaft mounted upon the automobile. .5 inthe central verticabplane of the wheel.

rotatable or fixed fronirotation, avertically and .horizontally adjustable yoke carrying an idlerpulleyon anaxis transverse to the-' shaft, said pulley. being-inside said-belt, and I said yokeebeing" adapted by. horizontal fad- ;just-ment to hold va-rioussized-pulleys.

3.;'lnpcombination'yvith an automobile and V a driving Wheelgt'hereof, an 'endlessbelt passing peripherally, around thewheel being of .greaterlength than thewheel circumfer .ence-, a' gshaft .mounted iupon{thegautomobile V in the central verticalIplane; of:the-, heel, a yoke on. the endof the. shaft, .anidleri shaft carried by'the yoke, iand ga n: i-dleron said 5 7 shaft, theyoke beinglmount'ed' onf the first -me'ntionedtshaftto be vertically and hori- -zontally adjustable'thereon and comprising two: members adjustable -vvith-f-.relation; to r i in the plane of. the Wheel, a. roller carrying xbracketmounted on. the endgqf the shaft and each other to Widen or'n'arrovvthe Widthof a i -.fthefyoke. f- 3 I f.

4=.- In combination with'an automobile and j driving Wheel thereof, an .ejndles'sibelt "passing peripherally, around the heel, bein-g of greater length thanthe wheel jci'rcum-e fer'ence, a longitudinal shaft mounted upon 1' 5. the automobile withits axis. substantially" embodying a pair of bracket members laterally adjustable With relation to each other and adjustable With relat'lon'to the shaft,a

transverse roller carried between 'said bracket members and inside said belt.

5. In a device of the character described, a bracket carrying member, a bracket comprising tWo separate parts individually adjustable on said member and one of the parts 10 removable from'said member, and a pulley shaft carried by and betvveen isaidbracket parts.

In Witness that Iv'claim the, foregoing I have hereunto subscribed my name. this 13th day of May, 1818. v i l
